comments between multilined parenthesis

[t3rn0]

If the list (tuple, dict, call, ...) is written across multiple lines there can be comments to certain elements of the list:

source = [
    # c1
    a,
    b,  # c2
]

If we parse-unpase it the comments will go out of the list. This may result in the loss of some potentially important info:

# c1
# c2
uparsed = [a, b]
